NCT05714553 · STUDY IN CONTEXT

NUC-3373 in Combination With Other Agents in Patients With Advanced Solid Tumours

Draft scope assessment: unclear. Attached because the study's own record names MSI-H. The study was not selected for this indication by its sponsor, and its eligibility has not been reconciled against this page in full. Found by searching ClinicalTrials.gov for this cancer type, restricted to studies that have posted results to the registry. No FDA notice, FDA label or NCI summary held by this site cites this study. Because the search asked for posted results, studies without posted results were never looked for, so their absence from this page means nothing.

Linked outcomes

Measures are not ranked. Open each original source section for treatment groups, denominators, units and results.

primary · POSTED

The outcome measure presented is the number of DLTs per module

The safety population was used and consisted of all patients who received at least one dose of study treatment (n=13 in Module 1 and n=4 in Module 2).

→

secondary · POSTED

Objective response rate, defined as the percentage of patients achieving a complete (CR) or partial response (PR) to treatment. Response was measured by MRI scan and assessed per Response Evaluation Criteria in Solid Tumors (RECIST v1.1) criteria in Module 2 and by immune RECIST (iRECIST) criteria in Module 1: CR= disappearance of all target lesions PR= at least a 30% decrease in the sum of the longest diameter of target lesions

The evaluable for response population was used and included all patients with measurable disease at baseline who had undergone at least two cycles of treatment, received at least 75% of planned treatment over the two cycles, and undergone a post-treatment objective disease assessment.

→

secondary · POSTED

Disease control rate, defined as the number of patients achieving a response (CR or PR) or stable disease (SD) as their best overall response. Disease control was measured by MRI scan and assessed using Response Evaluation Criteria in Solid Tumors (RECIST v1.1) criteria in Module 2 and immune RECIST (iRECIST) criteria in Module 1: CR= disappearance of all target lesions PR= at least a 30% decrease in the sum of the longest diameter of target lesions SD= neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease

    This Module is designed to evaluate the tolerability and the overall safety profile of NUC-3373 (1875 mg/m2) + LV (400 mg/m2) + pembrolizumab (200 mg) in the treatment of patients with advanced solid tumours (dose validation phase). NUC-3373 and LV will be administered on Days 1, 8 and 15 and pembrolizumab will be administered on Day 1 of 21-day cycles. The dosing schedule may be adjusted based on emerging data with agreement from the Safety Review Committee. Following completion of the dose validation phase, expansion cohorts may be initiated at the selected dose level.
